I have a DLL which I am trying to link in debug mode.  To that end I've specified the multithreaded debug DLL version of the runtime lib which, if I've read the docs correctly, should leave me linking to MSVCRTD.LI

My DLL is also linking to a static lib which was built using LIBCMT.LIB.  When I try to link I get the following error

 LIBCMT.lib(crt0.obj) : error LNK2019: unresolved external symbol _main referenced in function _mainCRTStartu

To get around that, I specified that the linker should ignore libcmt.  Now I get the following errors when I link

 librib.lib(illum.o) : error LNK2001: unresolved external symbol ___mb_cur_ma

But if I run 'dumpbin /exports' on the MSVCRTD.LIB file in VC++.NET's Vc7\lib folder, it shows an export for ___mb_cur_max.  So why isn't the linker finding it

Note that the problem goes away if I build my DLL using the non-debug multithreaded DLL version of the runtime library
